Cloth 26 serves other useful purposes in addition to `diffusing the owof air into the interior of the goggle and thus minimizing the wearersconsciousness of the incoming air. It also acts asa filter for dustorany other foreign material which it may be desirable to exclude from thewearers eyes. Furthermore, if the goggle is to be used for darkadaptation purposes, in which case lens 2i) will comprise dark redmaterial, y

cloth 26 should be of such color and texture as to exclude all undesiredlight. It should be pointed out, however, that the invention is in noway limited to the use of diffusing means or to the particular mountingmeans therefor shown in the land the interior portion of the goggle, butnot to nose chamber I5 and the wearers nose. The means for accomplishingthe latter result are shown particularly in Figs. 1, 2 and 4. Shield 35,preferably of the same material as the remainder of frame Ill, ismounted on the front thereof as by means of a suitable cement, and formswith the front of frame I an additional chamber 36. Shield 35 isprovided with a plurality of internal nubs 33 adapted to maintain it inspaced relation with frame I0. A plurality of apertures lil in the upperpart of nose-engaging portion I6 provide communication between theinterior of the goggle and air chamber 36. Communication between chamber36-and nose chamber I 5 may be provided by means of any suitable one-wayor flutter valve, and an example of a satisfactory valve device is shownparticularly in Figs. 1 and 2.

Frame I0 is molded initially with valve-mounting means comprising aplurality of ribs 42 interspersed with apertures 44 and connecting witha central rim 45. Valve stem 46 of valve 55 is adapted to engage in rim45 and is provided with an enlarged head 48 which will prevent itswithdrawal therefrom. Valve 50 is preferably made of a relatively thin,flexible material such as rubber and should be sufficiently light andflexible to offer minimum resistance to the passage of air throughapertures 44 during inhalation by the wearer of the goggle, but shouldat the same time be sufficiently firm to seal said apertures at allother times.

Itwill now be apparentthat each time the wearer of the goggle of theinvention inhales through his nose, he draws air through diffusingelement 26 into the interior of the goggle, and thence through apertures40 into chamber 36, whence it passes by way of apertures 44 and valve 50into nose chamber I5 and the nose of the wearer. It will also beapparent that the oneway action of valve 50, together with the sealed tof nose chamber I to the face of the wearer, serves to prevent exhaledair from returning to the interior of the goggle and thus insuresmaintenance of the desired fog-free condition of lens 2U.'

At .the lower part of nose chamber I5, there is provided a further valveassembly similar in function to valve 5I) for purposes of exhalation.Any convenient one-way valve may be used, and the illustrated examplecomprises ribs 52, apertures 54, central rim 55, valve stem 56 providedwith enlarged head 58, and valve 6I) corresponding in construction andaction to valve 5D. There will preferably be provided also a protectingrim 62 for valvel which alsoacts to deiiect exhaled air and prevent itfrom striking the outer surface of lens 20. If the goggle is designedfor use at extremely low temperatures, rim 62 may be substantiallyincreased in length in order to lessen the possibility of congealing themoisture in the exhaled air, which might tend to prevent valve fromsealing apertures 54 properly during inhalation. It will be noted,however, that valve 60 and its mounting means are necessary only topermit the wearer of the goggle to exhale through his nose, and may bedispensed within a simpler embodiment ofthe invention. In such case, thelower part of nose chamber I5 will be permanently sealed and the wearerof the goggle will have to exhale at all times through his mouth.

Any suitable means may be employed for mounting the goggle of theinvention on the head of the wearer, but the arrangement shown in Figs.l and 4 has been found particularly satisfactory. Straps 64 engage inslots 65, preferably T-shaped and lined with suitable grommets 66, inlens 2B, and are provided at their inner ends With a suitable lug orbead 68 adapted to prevent withdrawal through slots 65. If desired, aslotted washer element 69 may be used to insure sealing of slots $5against the passage of air therethrough during inhalation. Additionalsupport may be provided if desired by means of ears 'Ill at the outerends of frame, Ii) provided with transverse slots 72 through whichstraps B4 pass in encircling the head of the wearer. The invention is inno way limited to this mounting arrangement, however, and manysatisfactory variations therein will be readily apparent to thoseskilled in the art.

Since certain changes may be made in the above construction anddifferent embodiments of the invention could be made without departingfrom the scope thereof, it is intendedthat all 5 matter contained in theabove description or shown in the accompanying drawings shall beinterpreted as illustrative and not in a limiting sense.
